Linus Torvalds has picked up one of Apple's new Intel-based Mac minis to play with, but the Linux creator still prefers Apple's old PowerPC architecture for his primary desktop machine. "I'm actually still running a G5, but I also have a Mac mini," Torvalds revealed today in an e-mail to ZDNet Australia. "I like the design, and it's the right form-factor to be a replacement machine for my wife and daughter, but sadly, Apple screwed up the firmware in various stupid ways."
